How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. The work itself takes an hour or two for a single kitchen, longer for a large or complex system. Getting kit into a London building takes planning, so let us know where we can load and park in Lower Holloway.
- The visit is arranged for when the kitchen isn’t busy.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease readings are taken at set points using WFTT or DTT.
- We photograph the test points and record any sections we cannot reach.
- We send a report setting out the readings, pictures and next steps.
Before we arrive
- Let us know when the site is closed or quiet
- Mention any sign-in, permit or induction we need
- Tell us where we can park and unload

Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

TR19 inspection for kitchens and businesses in Lower Holloway
BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Those are minimums, and grease readings help set the real interval. The work covers deposit thickness tests, access surveys and insurer audits, and common reasons people get in touch are extracts that may be over the 200 micron mean and systems that need surveying before cleaning.
Kitchens in Lower Holloway, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Managing agents and facilities teams in Lower Holloway
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
What affects the cost of TR19 inspection
The quote reflects the site in front of us. We consider:
- Whether it’s a one-off visit or part of a schedule
- The size of the system
- How many systems or sites are involved
- Where the site is and how we reach it
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
What we need to know
Photos let us diagnose from a distance. Try to include:
- When the site is open and when it’s quiet
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- The postcode and the type of business
We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, phone us on 0345 646 2711 or email us.
Lower Holloway: your questions answered
Does London parking affect a job in Lower Holloway?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, typically makes it simpler.
Can a school canteen extract in Lower Holloway be done out of term time?
Yes, out-of-term visits are normal for schools. With about 53 schools and colleges on the FSA’s register within roughly a mile and a half of Lower Holloway, it pays to plan holiday dates ahead. Send us your term dates when you phone us on 0345 646 2711 or use the quote form, and we’ll fit the work in.
What is grease thickness testing?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, and set against the TR19® Grease figures.
Is TR19 a legal requirement?
No. TR19® is a specification, not a statute. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so it matters in practice.
How often should grease be tested?
It depends on how heavily the kitchen cooks. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and testing shows if your kitchen needs more.
How much notice should we give?
Earlier is better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
Leave it or put it right?
If there’s a fire or a claim, your insurer may ask for TR19 records. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. For a site in Lower Holloway, fitting the work in overnight now is far easier than closing at short notice later.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.

When to call us in Lower Holloway
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and grease in the extract is part of that risk.
The symptoms we are asked about most include:
- Extracts that may be over the 200 micron mean
- Extracts that have never been grease tested
- Insurance renewals needing proof of TR19 cleaning
- Post-clean verification after another contractor’s clean
A kitchen near Caledonian Road & Barnsbury station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
What your quote should include
- When they can work, and whether that’s outside your opening hours
- If they look at the system before pricing
- What happens if part of the system cannot be accessed
- How VAT is shown on the quote
What TR19 inspection cannot fix
Before you book, it helps to know what’s not included:
- A faulty or failing extract fan
- The responsible person’s own fire risk assessment
- Hidden runs that need access panels first
Not sure which it is? You can ring 0345 646 2711 or email us and we’ll tell you honestly before you book.
What the work covers
- Wet film thickness tests
- Post-clean checks

Kitchen extracts in Lower Holloway
The FSA’s food hygiene register includes about 183 bars, pubs and nightclubs and about 47 hotels, B&Bs and guest houses within 1.5 miles or so of the middle of Lower Holloway. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Lower Holloway sits within the area of London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. In Lower Holloway, food businesses are inspected by environmental health officers from Islington council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Healthcare kitchens, like those at hospitals such as King's College Hospital Charity (about 0.5 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands. A hall kitchen that only cooks for events, whether near St David or elsewhere in Lower Holloway, still needs its extract cleaned, just less often.

What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
